Altostratus cloud

We've now learned that cirrus clouds are thin wispy stringy clouds way up high in the sky,
cumulus clouds are big and puffy, almost like cotton balls,
cumulonimbus clouds are tall mushroom shaped clouds that are seen during storms,
stratus clouds are flat hazy foggy clouds that sometimes have light rain,
nimbostratus clouds are big, hazy and dark and are a sign of rain,
and cirrostratus clouds are very high up in the sky and flat and hazy.

Another type of cloud is called an altostratus cloud.
Just like stratus clouds they are flat and hazy, but they are not as high as cirrostratus clouds and not as low as stratus clouds.
They are in the middle of where stratus and cirrostratus clouds are.

Sometimes altostratus clouds have something called virga which is like rain or snow that never reaches the ground.
It leaves the cloud like rain, but evaporates or sublimates back to water vapor before it gets to the ground.
